“…During the study period, the common factors affecting seedling health were Powdery mildew (Fungal disease caused by Podosphaera xanthii ) and Cottony cushion scale (Insect pest, Icerya purchase ), where A. etbaica and A. asak were the least affected species, respectively. Likewise, Borah et al, (2012) also found powdery mildew affecting Acacia species in nursery and Royal Botanic Gardens, Kew in its Bulletin Vol.1889 (32) stated cottony cushion scale loving Acacia. However in general, all of the species were affected from mild to medium levels but managed to grow and survive effectively.…”

Southwestern Saudi Arabia is described by a unique ecosystem and composed of apicultural landscapes where nearly 70% of the beekeeping activities are concentrated. However, this economically important resource is under continuous degradation threat urging restoration. Besides, profound information on the possible major biological components of future restoration; nursery level performances of the native plants, Acacia species is lacking. Hence, the study was aimed at evaluating performances of selected native Acacia species at nursery level as candidate biological tool for apicultural landscape restoration. For this, nine native Acacia species’ seedlings were prepared in accordance to appropriate techniques of nursery operations recommended for arid areas. Meanwhile, species were evaluated and compared based on some performance parameters. Accordingly, significant (P < 0.005) variations were observed among the species in shoot height, collar diameter, height to collar diameter ratio, number of leaves and seedling survival. Acacia origena Hunde, A. gerrardii Benth., and A. johnwoodii Boulos. were superior over the others in most parameters while A. etbaica Schiweinf. and A. asak (Forssk.) willd. were less vulnerable to chanced pathogens. Generally, nursery level performances of all Acacia species under experimentation were within the acceptable range and showed a remarkable score which may lead them to be considered as competent biological tools in the incorporation of the genotypes in apicultural landscape restoration efforts.
